Chemical Dosing Pumps

Versatility

SPECIFICATIONS BL Series

Blackstone pumps have been designed to meet the ever chang-ing needs of industry. To accommodate diverse applications, the pumps can be easily mounted anywhere in your plant with their broad, flat base and mounting holes for tank, shelf or floor mounting (horizontal). The rear of the pump housing also pro- vides mounting holes to facilitate vertical mounting: wall, tank or machine. With the pump valve assembly and unit controls both located on the front of the pump, there is never a problem with installation or flow adjustments.

Simple Operation

Weight Approx. 3 kg (6.6 lb.)

Blackstone pumps are equipped with a single control for pump output. The external Flow Rate Control (potentiometer) on theface of the pump allows you to adjust the percentage of flowfrom 0 to 100% of the pump's rated capacity. This feature elimi- nates the need to worry about stroke lengths and power settings. An LED indicator lights up each time a stroke begins. This allows the user to assess the stroke rate from a distance.

High Quality Materials

BL 10-1 10.8 LPH flow rate, 110/115 Vac power supply

Blackstone pumps have been manufactured with the highest level of mechanical precision, from materials chosen for theirinherent ability to resist the effects of aggressive chemicals.When you select a Blackstone pump, you are eliminating the time consuming effort involved in picking the right material for your application.Blackstone pumps are supplied with the highest quality materialas standard equipment, not optional. The diaphragm utilizes one-piece construction of PTFE, which unlike conventional lami- nated diaphragms will stand up to the test of time and wear. Ball valves are constructed in glass. The pumphead and O-rings areall made of PVDF, PTFE and FPM/FKM which offer unsurpassedresistance.

Rugged Design

Blackstone pumps are completely sealed during assembly and offer IP65 protection against splashes and spills providing excel-lent protection even in hostile environments. The fiber-reinforcedpolypropylene housing stands up to aggressive chemicals while offering superior strength under tough industrial conditions.
